Attorney General K K Venugopal, appearing for the Centre, said he was opposing the PIL on various grounds, including that an inquiry has started after the FIR was registered.

The Centre today opposed in the Supreme Court a PIL seeking an independent probe and deportation of billionaire jeweller Nirav Modi in the over Rs 11,000 crore PNB fraud case, saying an FIR has been lodged and a probe was on.

A bench comprising Chief Justice Dipak Misra and Justices A M Khanwilkar and D Y Chandrachud said it would not say anything on the matter now and listed the PIL filed by lawyer Vineet Dhanda for further hearing on March 16.

Attorney General K K Venugopal, appearing for the Centre, said he was opposing the PIL on various grounds, including that an inquiry has started after the FIR was registered.

The PIL has made Punjab National Bank, Reserve Bank of India and the ministries of finance and law and justice as parties. It has sought a direction for initiation of deportation proceedings against Nirav Modi and others allegedly involved in the banking fraud, preferably within two months.

The plea has asked for a special investigation team (SIT) to probe the banking fraud, allegedly involving billionaire jewellers Nirav Modi and Mehul Choksi. It has also sought a probe into the role of the top management of the Punjab National Bank (PNB).

The CBI has already registered two FIRs -- one on January 31 and another a few days ago -- against Nirav Modi, his relative Mehul Choksi of Gitanjali Gems and others for allegedly defrauding the PNB of about Rs 11,400 crore.

The plea has sought a direction to the finance ministry to frame guidelines on the grant and disbursal of loans involving big amounts.

"Issue an appropriate writ, order or direction directing the Finance Ministry and the RBI to frame guidelines in granting of the loan of the 10 Crores and above to ensure safety and recovery of such loans," the PIL has said.

It has also sought the setting up of an experts' body to deal with cases of bad banking debts in the country. Besides, the petition seeks framing of rules for the recovery of loans from the defaulters within a stipulated period, even by attaching their properties and auctioning them in the open market.

In his PIL, Dhanda has asked for a direction to fasten liabilities on the employees of a bank for sanctioning loans on the basis of deficient documents and said loans should also be recovered by attaching the properties of such bank officials even after their retirement.

Another plea filed by Sharma on a similar issue has not come up for hearing yet.

Sharma, in his plea, has said the SIT should consist of retired judges of the apex court and said that the banking fraud has caused serious injury to the general public and the state's treasury. It should be investigated not by an agency "being controlled by the political leaders/authorities", he has said.

The plea has alleged that loans were issued in the case without following RBI's financial rules and regular systems.
